ATTACHMENT FOR CORN PIGKERS.

Application filed April 18,1925. Serial No. 24,177.

To all whom it may concern:

Be it known that I, HENRY MAGNEss, a citizen of the United States, residing at Colton, in the county of Minnehaha and State of South Dakota, have invented certain new and useful Improvements in Attachments for Corn Pickers, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an attachment for corn pickers but has relation more particularly to an attachment of this kind disclosed in my pending application Serial No. 10,386, filed February 19, 1925, wherein is employed a series of propeller blades to maintain the gathered ears in proper position with respect to the rolls and to assure the ears travelling forwardly thereof, and it is an object of the invention to provide novel and improved means for supporting said blades whereby the same will have requisite oscillating movement to assure the effective functioning of the blades.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved attachment for corn pickers whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a fragmentary vertical sectional view taken through an attachment constructed in accordance with an embodiment of my invention;

Figure 2 is a sectional view taken substantially on the line 22 of Figure 1 with certain of the parts omitted;

Figure 3 is an elevational view of a mounting for the supporting rod for the blades.

As disclosed in the accompanying drawings, R denote the rolls of a conventional type and driven in a well known manner and at opposite sides of which are the side boards 1 of requisite dimensions. Rotatably supported above and slightly to the rear of the rolls R is a fan F operating as preferred. A shaft S is rotatably supported by the forward or discharge end of propeller blade 5 the-lower marginal portion of which being provided therealong with the longitudinally spaced and forwardly inclined depending fingers 6. Operatively engaged with the forward end portion of each of the blades 5 is an end portion of the pitman 7 which is also operatively engaged with a crank 8 of the shaft S.

Each of the blades 5 at a point slightly in advance of its longitudinal center has pivotally connected therewith, as at 9, the lower end portion of an upstanding arm 10 the upper end portion of which being provided with a cross head 11 through which is freely disposed a supporting rod or bar 12.

Each end portion ofthe rod or bar 12 is disposed through a bearing 14 the extremities of which normally resting upon the upstanding posts 15 carried by the extremities of a cross member 16 provided at the upper end of a pillar 17; This pillar 17 rests upon the upper edge of a side board 1 and is bolted or otherwise secured thereto, as at 18.

The cross head 16 outwardly of the pillar 17 has disposed upwardly therethrough the rods 19 which are also freely disposed through the bearing 14. These rods 19 above the bearing-14 are provided with the heads or enlargements 20 and between said heads 20 and the bearing 14 are interposed the expansible members 21 herein disclosed as coil springs encircling the rods 19.

In the operation of the device, the arms 10 operate as the shaft S rotates to cause the blades 5 to oscillate in a manner whereby the corn delivered upon the rolls R will be efiectively fed forwardly therealong-anol maintained in desired position with respect to said rolls and the springs 21 permit the yielding upward movement of the blades 5 or more particularly the bearings 14 as may be necessary by the ears passing forwardly of the rolls B. This assures an effective operation of the blades 5 with the liability of breakage 'of the parts associated therewith reduced to a minimum.

From the foregoing description it is thought to be obvious that an attachment for corn pickersv constructed i raccordance With my invention is particularly Well adapted for use by reason of the conx' enie'nce' and facility with which iemaybe assent bled and operated, and it Will also be obvious that my invention is susceptible ofsome change and modificationv Withoutdeparting from the principles and spirit thereof and for this reason I do not Wish to be understood as limiting inyself to the precise rangement and formation of the several partsherein shown .1n carrying out my. 111- ,vention in practice except. as hereinafter 2 therOllS and extending transversely thereof,

arms freely engaged With said rod and depending therefrom, each of said arms being ope'rative'ly engaged with a blade, bearings for the rod, means for oscillating the blades, and meansfo'r supporting the bearings for yieldable upward movement.

2.--In'combination with a set of husking rolls, a propeller blade positioned above each of the rolls, a rod positioned above each of the rolls and extending transversely thereof, arms freely engaged with said rod and depending therefrom, each of said "arms being operatively engaged with a blade, and means for oscillating the blades, the 'p'i'votal connection between an arm and a blade being at a point in advance of the longitudinal center of the blade. 7

In testimony whereof I hereunto affix my signature. w HENRY. MAGNESS.
